Second-hand purchases save 40-80% vs new across most categories. Furniture often 60-80% off. Electronics 30-50%. Clothing 50-90%. Annual impact depends on shopping frequency. Plus environmental benefit — manufacturing accounts for 60-90% of product carbon footprint.
What the result means
Lifetime savings from second-hand habit. Plus environmental benefit (not in calc but real). Some categories don't suit second-hand (mattresses, undergarments) — apply to suitable categories.
Quick example
With new item cost of 200 and second-hand cost of 80 (plus items per year of 6 and years projected of 10), the result is 7,200.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter New Item Cost, Second-Hand Cost, Items Per Year, and Years Projected. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.
What's happening under the hood
Per-item saving × items × years. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Running the sensitivity
Energy prices, usage patterns, and grant availability all move the payback figure. Test at least two scenarios — current rates and a rate 20% higher — to see whether the decision holds up across plausible futures.
What this doesn't capture
Carbon reduction, health benefits, and local air quality have real value the financial figure doesn't price. The calculation gives the money side honestly; for the full picture, note the non-financial benefits alongside.
Second-hand vs new produces lifetime savings based on the inputs provided.
